Please also review the following frequently asked questions:

My invention is the best in the world, how much will you pay me for it?

We do not pay money for clients’ inventions. As a patent law firm, we cannot invest in clients’ inventions and represent them at the Patent Office.

How much is the cost of a patent?

The government filing fees are approximately $800. If you need us to write the application, plan on spending about $5000 on writing and submitting an application. Costs vary from project to project. You should budget at least another $3000 to defend the case after filing. $10,000 is not an unreasonable.

What is the deadline to file a patent application?

You should file for a patent before you disclose your invention to third parties. If the invention has been shown publicly, you may still be able to pursue patent protection in the US, but it is best to file before disclosure. Once offered for sale inventions cannot be protected by a patent.

Can every invention be protected by a patent?

No, only a small subset of inventions are patent eligible. Many highly valuable ideas cannot be protected by a patent because they fall into a category disfavored by U.S. patent law. Other inventions are not considered sufficiently innovative to merit protection. We recommend that clients obtain a patentability opinion before beginning work. Our office charges $800 to $1500 for such opinions, depending on the details of the case.

How long does it take to get a patent?

At least 18 months or longer depending on how busy the Patent Office is. For the last few cases registered in our office, the applications were pending for: 4 years, 18 months, 2.5 years, 3 years, 2.5 years.

Are there costs for maintaining a patent?

Yes, the patent office has a schedule of maintenance fees, which are due at three anniversaries of registration. Current fees are as follows: 3.5 years ($800), 7.5 years ($1800), and 11.5 years ($3700).
